Pons Cestius

The Pons Cestius (Italian: Ponte Cestio, meaning "Cestius' Bridge") is a Roman stone bridge in Rome, Italy, spanning the Tiber to the west of the Tiber Island. The original version of this bridge was built around the 1st century BC (some time between 62 and 27 BC), after the Pons Fabricius, sited on the other side of island. Both the pontes Cestius and Fabricius were long-living bridges; however, whereas the Fabricius remains wholly intact, the Ponte Cestio was partly dismantled in the 19th century, with only some of the ancient structure preserved.

The Pons Cestius is the first bridge that reached the right bank of Tiber from the Tiber Island. Whereas the island was long connected with the left bank of the Tiber and the heart of ancient Rome, even before the pons Fabricius, the right bank (Transtiber) remained unconnected until the Cestius was constructed. Several prominent members of the Cestii clan from the 1st century BC are known, but it is uncertain which of them built this bridge.
